SPECIFICATION forming part of Letters Patent No. 516,022, dated March 6, 1894.

Application le September 16, 1893. Serial No. 485,659. (No model.)

To a/ZZ whom it may concern:

Be it known that l, ROYAL ZnLorns PooL- ER, of St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and Improved Rotary Engine, of which the following is a full, clear, and eract description.

The object of the invention is to provide a new and improved rotary engine, which is simple and durable in construction, Very effective in operation and arranged to utilize the motive agent to the fullest advantage.

The invention consists of certain parte and details, and combinations of the same, as will be hereinafter described and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parte in all the gures.

Figure l is a transverse section of the improvement. Fig. 2 is a sectional side elevation ot the cylinder. Fig. 3 is a side elevation of the piston; and Fig. et is a transverse section of the same on the line 4 4 of Fig. 3, with the cylinder in section.

The improved rotary engine is provided with a cylinder A made in two parts A and A2 fastened togetherby suitable bolts B. The cylinder parts A' and A2 are formed at their lower ends with bases Asand Az respectively, adapted to be set on a suitable foundation. The cylinder parts A and A2 are also provided with integral heads A5 and A6 respectively, in which is journaled the main driving shaft C connected by suitable mechanism with the machinery to he driven.

On the shaft C within the cylinder A is secured a piston D made in the shape of a wheel and provided with a rim D', and an annular transverse partition D2 extending from the hub to the rim at or near the middle thereof, as plainly illustrated in Figs. l and 4:. The piston D is also provided with wings Ds so as to form steam compartments on opposite sides of the partition D2. In each wing DS are fitted to slide longitudinally, packing bars E pressed outward in contact with the inner faces of the heads A5 and Ai by the force of live steam passing into the bearings for the said bars in the respective wings DS. In order to permit the the packing bars,

live motive agent to act on the said wings D3 are per- I forated as at D4 as is plainly illustrated in Figs. l and 4, to allow the steam to pass into the bearings for the bars to push the latter outward. In the head A5 are arranged the steam inlet ports a and a', located diametrically opposite each other, as plainly illustrated in Fig. 2, and in the said head are also arranged the exhaust ports b and b located diametrically opposite each other and standing at right angles to the ports a and a. Similar inlet ports o2 and 0.3 are arranged in the other head A6 and like exhaust ports b2 are located in the said head A6. The ports a and o. open into a channel A7 formed in the head A5 and the ports a2 and a3 are likewise connected with each other by a channel AS arranged in the head A5. The channels A7 and A8 are provided with pipes F and F respectively, connected with a steam supply pipe Fzprovided with a suitable throttle valve G and leading from a boiler or other suitable source of steam supply. The exhaust ports b, b', and b2 discharge into exhaust pipes H leading to the outside; f

The operation is as follows: W'hen the throttle valve G is opened, live steam passes through the pipe F2 into the branch pipes F and F and from the latter into the channels A7 and A8 and through the ports a a2 and a', 0.3 into the registering steam compartments formed in the piston D, as above described. The motive agent acting on the wings l)3 in the said piston causes the latter to rotate so that the main driving shaft C is turned and power is transmitted throughout the machinery.

1t will be seen that when a compartment is supplied with live steam, the rear wing will cut ott the steam finally by passing over the ports a, a', a2 or a3, so that this compartment now connects with the next following exhaust port b to permit the steam to exhaust throughthe respective ports Z9, b', or b2. On the next quarter revolution this compartment again takes steam in the next inlet port and so on, so that each compartment receives live steam twice on each revolution of the piston.

It will be seen that by this construction no valves, gates or abutments whatever are used, and the force of the motive agent is utilized to the fullest advantage and without danger of any of the parts getting out of order.

IOC

Havingthus fully described myinvention, I claim as new and desire to secure by Letters Patent- 1. A rotary engine comprising a cylinder provided on opposite sides with inlet and exhaust ports, and a piston made in theshape of a wheel and provided with a transverse partition extending from the hub to the rim at or near the middle thereof perforated wings forming steam compartments on opposite sides of the partition and packing bars in said wings substantially as described.

2. A rotary engine, comprising a cylinder made in two parts having integral heads, each provided with diametrically-arranged steam inlet ports and steam exhaust ports, and a channel for connecting the steam inlet ports with each other, and a piston made in the shape of a wheel and mounted to turn in the said cylinder, the said piston being provided with a rim, an annular partition and Wings forming steam compartments adapted to alternately register with the said inlet and exhaust ports, substantially as shown and described.

3. A rotary engine, comprising' a cylinder made in two parts having integral heads, each provided with diametrically-arranged steam inlet ports and steam exhaust ports, and a channel for connecting the steam inlet ports with each other, a piston made in the shape of a wheel and mounted to turn in the said cylinder, the said piston being provided with a rim, an annular partition and wings forming steam compartments adapted to alternately register with the said inlet and ex` rhaust ports, and packing bars fitted to slide ports, packing bars tted to slide in bearings in the said piston, the said wings being provided with perforations to connect the steam compartments with the bearings for the said bars, to force the latter outward in contact With the heads by the pressure of the steam, substantially as shown and described.
